This is actually a very old insult with deeper meaning that has been largely forgotten. I suspect it goes back hundreds of years and used to be used a LOT more before political correctness (even on several episodes of the tv show "MASH"). Based on the definitions here, I don't think the younger crowd understands that calling someone a "goldbricker" actually means to call someone a lazy selfish jew. For thousands of years of history, many jews were in banking and finance, which is not an industry based on manual labor. Thus, A strong stereotype of the jews arose, as them being too lazy to lift a finger and do some actual physical work for their money, but having plenty of energy to carry their bricks of gold "earned" from merely making and collecting loans with interest (a biblical reference from Jesus reinforces this viewpoint). This used to be one of the WORST insults you could hurl at someone you're working with, because it implies selfishness PLUS laziness PLUS making money for doing nothing PLUS making money on the labor of others, PLUS having extreme indifference to others, all while others around you are toiling hard. The common jewish surname of "Goldman" is heavily tied to this long running stereotype, historically possibly not by the choice of many jews.
